| Abstract
|
| [Objective] We aim to establish a loop-mediated isothermal amplification(LAMP) technique for the rapid differentiate of Whitmania Pigra Whitman from other closely related species.[Methods] We designed LAMP primers based on the mitochondrial cytochrome c oxidase I(COI) gene sequences of Whitmania Pigra Whitman. Subsequently, LAMP amplification of leech was performed at a constant temperature of 64℃ using the newly designed LAMP primer sets.[Results] After the reaction, ladder-like bands were observed in positive samples by electrophoresis, whereas control groups are produced without bands. After adding 0.2 μL 10 000×SYBR GreenⅠdye, the positive samples changed color from orange to green under both ultraviolet and natural light, while the control groups remained orange.[Conclusion] LAMP technology can be used for the rapid authentication of Whitmania Pigra Whitman, and provides technical support for the on-site identification of leeches in herbal market. |
